LUDLUM MODEL 500 PULSER PULSE GENERATOR GREAT CONDITION This auction is for a Ludlum Model 500 Pulse Generator. The Ludlum Model 500 Pulse Generator (pulser) provides the functions necessary for use in calibrating Ludlum radiation detection instruments as well as many other scaler/ratemeter instruments from other manufacturers. The adjustable output pulse rate is displayed on a three-digit LED readout. Potentiometers (both coarse and fine controls) and a multiplier switch provide rates from 1 to 9.9 x 106 counts per minute (cpm). Pulse amplitude is controlled by a multiplier switch and a LO/HI potentiometer, while pulse polarity is chosen by a selector switch. Amplitude may be varied between 0 and a negative or positive 5 volts; displayed on an analog meter. The high voltage of the instrument under test is displayed on an analog meter with markings of 0-2.5 kilovolts. This pulser looks to be in great condition. It turns on and all controls work great. I am unable to test it any further. This auction is for only what you see in the picture, Model 500 Pulser and a power cord. E-mail me with any questions you may have. I guarantee no DOA!! I accept PayPal. Buyer to pay $20 shipping/packaging/insurance costs. (International buyers must pay actual shipping + $15.00 packing.) Thanks for your interest.
